MITERe-BOX.

SPECIFICATION forming part of Letters Patent No. 638,620, dated December 5, 1899.

' Application filed September 11, 1899. Serial No. 730,159. (No model.)

T0 at whom it may concern:

Be it known that I, THEODORE BOOTSMAN, of Artie, in the county of Ohehalis and State of Washington, have invented a new and useful Improvement in Miter-Boxes, of which the following is a specification.

This invention is in the nature of an improvement on my prior patent, No. 624,745, dated May 9, 1899, and relates particularly to the means for locking the saw-guides at different angles and the means for holding said guides at different elevations.

Theinvention consists in the details of construction and arrangement of the parts,which I shall now describe, and then particularly point out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which like characters of reference indicate corresponding parts in all the views.

Figure 1 is a front view of the miter-box, with parts in section. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a vertical transverse section through the center of the box. Fig. 4.- is a detail horizontal section on line 4 4: of Fig. 1, and Fig. 5 is a vertical section on the line 5 5 of Fig. 2.

The base-frame a supported by short legs a and provided with thrust bearing-strips a for the work that is to be sawed, has secured thereon the horizontal bed a, the upright posts A, connected at their upper ends by the cross-bar S, and a cross-bar H, slidable vertically on the said posts, all as in my Patent No. 624,745 referred to above.

To the cross-bar H and at the middle thereof is fixedly secured in any suitable manner the vertically-extending steel or other metal tube R, which extends through and rises above the cross-bar S, and within such tube It is fitted a shaft B, which extends through the cross-bar H and up through the tube R, beyond the upper edge of the same, and is formed with a screw-thread at its upper end adapted to receive an adjusting and bearing nut B, bearing on the upper edge of the tub R, and a lock-nut B thereabove.

The horizontally-swinging arm T is secured at its inner end to the lower end of the shaft B, and the spaced-apart saw-guides P are adjustably secured to and suspended from said arm by headed bolts Z), fitted in elongated slots b in the arm. By this arrangement of -partst-hat is, by connecting the arm T with the shaft B the arm may be swung around in a horizontal plane to guide the saw for cuts of different angles, and in order to lock the saw in difierent angular positions I provide a semicircular gage-bar H,hinged to the crossbar H, as shown best in Fig. 2, and capable of being swung in a vertical plane. This bar H is formed with three or more elongated slots H, in which are received headed bolts or studs H andany one of these studs is adapted to enter a recess T on the upper face of the arm T, whereby to hold the saw-arm locked in adjusted position. In order to release the arm to change its position, thelever K is fulcrumed thereon, as at K, and the forward end of said lever lies underneath the gage-bar H, so that when the handle end of the lever is depressed the forward end thereof will raise the gage-bar and draw the bolt H out of the recess T, when the arm T may be swung as desired.

It is desirable to enable the saw-guides to be raised to various elevations, whereby to allow the work to be placed underneath the same, and to this end a split clamping-ring D, provided with a clamping-bolt D, surrounds the tube R and rests on the upper cross-bar S, so that when desired the tube R and the parts which it supports may be held raised at different elevations.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-- 1. In a miter-box, a support for the work, a horizontally-swinging arm carrying sawguides and held over said support, and a Vertically-swinging gage-bar arranged for looking engagement with said arm, as set forth.

2. In a miter-box, a support for the Work, upright posts on said support, a cross-bar be-' tween said posts, a second cross-bar therebelow and slidably fitted on said posts, a shaft extending through said cross-bars, a horizontal arm carrying saw-guides and secured to said shaft, and a semicircular gage-bar hinged about a horizontal axis to the lower cross-bar and arranged for engagement with said arm as set forth. 7

3. In a miter-box, a support for the Work, a horizontally-swinging arm provided with saw-guidesand held over said support, the said arm being formed with-a recess, a verticallyswinging gage-bar having a series of studs on its lower face any one of which is adapted to enter said recess, and a lever fulcrumed on said arm and arranged to raise said gage-bar whereby to withdraw the studs, as set forth. 4. In a miter-box, a support for the Work, upright posts on said support, a fixed crossbar connecting said posts, a second cross-bar slidably fitted on said posts below the fixed cross-bar, atube secured to the lower crossbar and extending up through the fixed bar, a shaft fitted in said tube and supporting saw-guides, the upper end of said shaft extending above the tube and being formed Wlth'SCIGW-thlGldS, a nut on such end and bearing on the upper edge of the tube, and a split clamp surrounding said tube and rest ing on the fixed cross-bar, as set forth;

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THEODORE BOOTSMAN,
